Abstract
A method and apparatus for manufacturing resilient, deformable serpentine products including a pair of form rolls (10, 12). The form rolls (10, 12) are generally circular in shape and include a plurality of intermeshing blades (56). The blades (56) have a plurality of teeth (62) each including a peak (70), a valley (74), and a central hollow region (64) that receives a shaft (90) for transferring a fluid thereto. The fluid is then conveyed from the shaft (90) through a plurality of grooves (80) on the surface of the blades (56). In one embodiment, the fluid is to aid in the forming process.
Claims21
A tool for forming deformable, resilient, serpentine products comprising:
- a pair of rotatable forming rolls that define a forming area therebetween in a region of intermeshing contact;
- a plurality of blades included in each of said forming rolls, each of said blades having a hollow inner region;
- one or more of said blades having a plurality of teeth spaced about its periphery, one or more of said plurality of teeth having a peak, a valley, and a forming surface lying therebetween;
- said valley having a groove formed therein, said groove being in communication with a passageway, the passageway serving to duct a fluid to the forming area which facilitates the forming of said serpentine product, said passageway extending from said valley to said hollow inner region.
A method of delivering fluids to a tool used for forming louvered serpentine fins comprising the steps of:
- providing a pair of rotatable wheel assemblies each having a plurality of blades, each of said blades having a hollow inner region and an outer surface,
- providing a plurality of grooves on said outer surface of at least one of said plurality of blades;
- providing a plurality of forming surfaces on said outer surface of said at least one of said plurality of blades;
- and
- transferring a fluid to said hollow inner region of one of said plurality of blades for conveying said fluid to said grooves for facilitating preparation of a work product being formed.
A form roll used in the formation of a deformable, resilient serpentine product comprising:
- at least one blade, said at least one blade having a generally hollow inner region;
- at least one tooth formed on the periphery of said blade;
- a pair of forming surfaces extending generally inwardly from said at least one tooth;
- a hollow tube located within said hollow inner region for conveying a fluid thereto;
- a passageway in communication with said hollow tube;
- and
- a groove formed on said tooth in communication with said passageway for expelling said fluid onto a workpiece.
